CV: Lutsenko Dmytro attended the Karazin Kharkiv National University (Kharkiv, Ukraine) from 1991 to 1996 and studied Biology, Human and Animal Physiology. He achieved his Ph.D.  in biology (Cryobiology) at the Institute for Problems of Cryobiology and Cryomedicine (Kharkiv, Ukraine). Since 1999, he works at the Institute for Problems of Cryobiology and Cryomedicine: Kharkiv as a researcher at the Department of Cryophysiology. He was part of the 21 st Ukrainian Antarctic Expedition, Academic Vernadsky station in Antarctica from April 2016  to April 2017. His main areas of research include: Study of the physiological mechanisms of an organism's adaptation to the cold. Research of mechanisms of the organism adaptation to stay in the conditions of Antarctica.

Presentation title: Some peculiarity of people’s adaptation during a long stay in the Antarctica

Abstract: We studied the some features of people’s adaptation during the wintering at the Ukrainian Antarctic station "Akademik Vernadsky". By the physiological responses the winterers were divided into 2 groups with a predominance of sympathetic or parasympathetic responses of autonomic regulation. Similar processes were recorded by us during the Cold Pressor Test, therefore we believe that cold is one of the main factors affecting the peculiarities of the vegetative regulation of the organism in the Antarctica. The analysis of several sleep parameters noted that for all participants, quasiperiodic changes in the total duration of the daily representation of sleep were observed. The changes in the parameters of sleep were the result of the interaction of "non-core" factors (chronotype, personal traits), as well as forced contact with cold, which affects sleep. We are grateful to the National Antarctic Scientific Center of Ukraine for supporting the study.
